Another short fluid capacity post, this time for the M1 Abrams. All versions of the M1 use the Honeywell AGT-1500 gas turbine engine and the Allison X1100-3B transmission.

The Under Armor APU (UAAPU) is fitted standard on the M1A2C1. Previous versions may have an APU mounted in the bustle rack as a retrofit, the UAAPU as a retrofit, or no APU at all.

The Abrams makes no provision for external fuel. Suck it up, buttercup.
